Order File for Audio Book

The file is probably DRM-protected. It is possible to remove the protection using a software program.

I am assuming you downloaded an audio book (an MP3 file), in which case you have to open any media/audio player app that you have installed on your Nextbook and it will find that file for you.

MP3 players can only play music and audio books files in mp3 file format. You can download mp3 music files from the Internet to your computer and then copy them to your MP3 player using the USB cable. For your CD collection, you need to convert your CDs to mp3 music files onto your computer or download them from the Internet and then copy them to your MP3 player after you have connected the USB cable to the MP3 player and the computer.
You can do this using Windows Media player and Rip the CDs - Media Player will create a MP3 music file for each music track. Click on this link for instruction on converting music files to mp3 file format :- http://www.fixya.com/support/r5798418-creating_transferring_mp3_music_files

Did you ever get this working? I'm seeing the same error when trying to transfer an audiobook checked out from the Dallas Public Library to my Samsung Galaxy Nexus phone.

I am having the same problem - never used to have this problem on previous versions of overdrive/itunes. Its loading all the files into the root directory of the ipod for some reason.

First download the driver from your player's manufacture's site. It will be under download tab or support tab.
Download and install driver, then restart pc

Then turn on device, then plug into pc, then go to my computer, then you should see your device there. Double-click on the device folder. Now you can see and will have access to all folders.
You can leave this page up, then go to the page & file that your book is on. click, hold, and then drag this file over to the audio book folder and release the button, it will transfer the book to the mp3 player audio book file.
You can also use windows media player 11 and sync your mp3 player to your windows media player and create a playlist or library and transfer them onto mp3 player as well

Hi.
I report a solution from Portable player FAQ, let me know if it works:
1. Delete the title in the Overdrive Media Console program.
2. Then log into the Audiobook site at http://e.hbpl.org and click on My Account, My eItems Checked Out, and click the Download button the website to re-download the book.
3. Transfer the newly downloaded parts to your player.

I was having the same problem when I used Overdrive Media Console to transfer my audiobook files to my Sansa. I updated the license and retransferred and even tried changing the USB settings on the mp2 player. What finally worked? Using Windows Media Player to sync the files instead. When I hooked up my Sansa I chose "use WMP to sync files" and then I dragged/dropped the audiobook files to the mediaplayer window. The audiobook now plays without any problems since WMP made sure the files have the latest subscription update code.

Audiobooks in WMA format have a restrictive DRM-license that does not allow their use on certain types of mp3 player. To use the WMA file that you already have, you will need to use an illegal DRM-stripper such as Tunebite - but, that's illegal.

You will have to stick to audiobooks that are in mp3 format - and even then, there are a few asterisks - you may not be able to resume where you left off without fast-forwarding. But at least you will be able to play the file.

FiXED!
Had the same problem
I fixed it on my e260. The solution: Drag and drop the mp3 file directly into your media player, skip the overdrive 'wizzard', you need to find the folder where the media is stored.
